Scientists at Rockefeller University have proposed that the orderly succession of events in cell division is governed by a master oscillator, coordinating with independent oscillators that control individual events. Their model suggests that this orderly orchestration is analogous to how our circadian rhythm syncs with the light-dark cycle in our environment.http://phys.org/news190878712.html

Tested in animal models, the system could dramatically advance scientists' understanding of the relationship between metabolic disorders and heart rhythm disturbances in humans that can lead to cardiac arrest and death, and provide a platform for testing new treatments to prevent or stop potentially fatal irregular heartbeats, known as arrhythmias.http://phys.org/news176138251.html
Medicine & HealthFri, 30 Oct 2009 16:18:05 EDTnews176138251Concurrent imaging of metabolic and electric signals in the heartCardiac rhythm disorders can result from disturbances in cardiac metabolism. These metabolic changes are tightly linked with specific cardiac electrophysiology (CEP) abnormalities, such as depressed excitability, impaired intra- and extracellular conductivities, wave propagation block, and alteration of conduction velocity, action potential amplitude, and duration. The altered electrophysiology eventually can lead to arrhythmias, fibrillation, and cardiac death; therefore, understanding the spatiotemporal complexity of the relationship between metabolism and electrophysiology is the challenge in developing new approaches for treatment of cardiac diseases.http://phys.org/news175777096.html
